The most likely scenario is that Microsoft will release about the same editions that shipped at the release of Windows Vista. Screenshots of current Windows 7 builds display the version that Microsoft is shipping to its partners as Windows 7 Ultimate which could be a hint that we will see a Windows 7 Ultimate edition. If Microsoft stays true to that strategy they will most likely release editions like Windows 7 Home Basic, Windows 7 Home Premium and Windows 7 Business as well.
In the DVD for Windows 7 there is are license.txt agreements for Starter, Home Basic, Home Premium, Enterprise, Business, and Ultimate.
Whether the final releases will be in those formats is unknown at this time.
I hope this helps,

I dislike all of these editions. I use Home Premium and it seems there is no complete difference between Business and Ultimate. They should just stuck with 2, like XP... or maybe even one. One Windows 7 and one Windows 7 server.
